Description

[0002] As an important part of modern transportation infrastructure, the construction of expressways is not only related to economic development, but also involves environmental protection, traffic safety and other aspects. In complex terrain conditions such as mountainous areas, tunnels have become an indispensable part of expressway design. During the construction of tunnels, a large amount of water will accumulate inside the tunnels, which needs to be discharged in time through drainage devices.

[0003] The existing tunnel drainage device can divert the pumped sewage through the diverter, and part of the sewage is diverted to the mixing mechanism through the diverter through the water pipe. While achieving moderate mixing of the sewage, it can also buffer the sewage pumped by high-pressure pumping, thereby indirectly avoiding the high-intensity pumping of the mud pump that may affect its service life and appropriately reducing the operation and maintenance frequency of the drainage device.

[0004] Although the existing tunnel drainage system can effectively buffer the sewage pumped by high-pressure pumps, the stirring mechanism is in direct contact with the tunnel water containing a large number of solid particles. With the continuous suction action of the pump, these solid particles are sucked into the stirring mechanism in large quantities, which not only interferes with the normal operation of the stirring mechanism, but may also enter the pump body and damage the internal structure, thereby shortening the service life of the entire device.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figures 1 to 11As shown, as an embodiment of the present invention, a tunnel drainage device for highway construction is provided, including a drainage pump body 100, a water inlet pipe 110 is fixed on the input end of the drainage pump, a hose 140 is connected to the water inlet pipe 110, one end of the hose 140 is connected to the suction assembly 200, a drainage pipe 120 is fixed on the output end of the drainage pump, a branch pipe 130 is arranged on one side of the drainage pipe 120, a hose 2 150 is connected to the branch pipe 130, a filter screen can be installed at the connection between the branch pipe 130 and the drainage pipe 120, the filter screen can filter the water discharged from the drainage pipe 120 into the branch pipe 130, so as to prevent the debris in the water from damaging the subsequent structure of the device and prolong the service life of the drainage device, and also includes: A rotating cleaning mechanism 400, wherein the rotating cleaning mechanism 400 is located directly above the suction assembly 200 and is fixedly connected to the outer wall of the suction assembly 200, and one end of the rotating cleaning mechanism 400 extends into the suction assembly 200 and contacts the inner wall of the suction assembly 200; A control mechanism 500, which is disposed on one side of the rotary cleaning mechanism 400 and is fixedly connected to the rotary cleaning mechanism 400, one end of the control mechanism 500 is connected to the branch pipe 130 through the second hose 150, and the other end of the control mechanism 500 is respectively connected to the suction assembly 200 and the rotary cleaning mechanism 400; The blocking mechanism 300 comprises an annular sleeve 310, a circular block 320 and a blocking assembly 330. The annular sleeve 310 is fixed to the bottom of the suction assembly 200 by bolts. The circular block 320 is located between the suction assembly 200 and the annular sleeve 310 and is rotatably connected to both. The other end of the rotating cleaning mechanism 400 is concentric with the circular block 320 and is fixedly connected thereto. A square groove 321 is provided in the middle of the circular block 320. A plurality of mounting grooves 322 are symmetrically provided at both ends of the circular block 320. One side of the mounting groove 322 is connected to the square groove 321. The blocking assembly 330 is equidistantly distributed in the square groove 321, and the two ends of the blocking assembly 330 are freely rotatably installed in the mounting grooves 322 located on both sides of the square groove 321. The drainage pump body 100 can quickly suck the accumulated water inside the tunnel through the water inlet pipe 110, the hose 140 and the drainage assembly 200, and quickly discharge it out of the tunnel through the drainage pipe 120. The multiple blocking components 330 can block the fixed particles entering the drainage assembly 200 to prevent them from entering the drainage assembly 200 and causing damage to the drainage pump body 100, thereby ensuring the drainage quality and efficiency of the drainage pump body 100 and extending the service life of the drainage pump body 100. Part of the accumulated water discharged from the drainage pipe 120 will enter the branch pipe 130, and the branch pipe 130 will discharge the accumulated water into the control mechanism 500 through the hose 150. The control mechanism 500 will quickly discharge the accumulated water into the rotating cleaning mechanism 400. The accumulated water can drive one end of the rotating cleaning mechanism 400 to rotate by being quickly discharged into the rotating cleaning mechanism 400. The one end of the rotating cleaning mechanism 400 can not only scrape the sludge retained on the inner wall of the suction and discharge component 200 by rotating, thereby ensuring the pumping quality and efficiency of the suction and discharge component 200 and improving the pumping efficiency and quality of the drainage device, but also drive the circular block 320 to rotate between the annular sleeve 310 and the suction and discharge component 200. The circular block 320 drives the multiple barrier components 330 to revolve, and the multiple barrier components 330 in the revolving state will contact with the solid matter in the tunnel. The particles come into contact, thereby triggering the free rotation of multiple barrier components 330, so that the multiple barrier components 330 simultaneously perform orbital and self-rotation motions, which can not only effectively intercept and separate the larger impurities in the accumulated water, play a role in pretreatment and filtration, but also protect the pumps, pipes and other key equipment in the drainage system from wear and blockage, ensure the smooth operation of the drainage system, reduce the burden on the drainage device, and extend its service life, but also form a dynamic filtration effect. When the barrier component 330 rotates, it can drive the lighter water or air around it to rotate, so that a layer of dynamic filter membrane is formed on its surface, making it difficult for the barrier component 330 to be blocked by impurities, further enhancing its ability to intercept solid particles, protecting the internal structure of the drainage device, and at the same time improving the durability of the drainage device, ensuring the smooth progress of drainage operations.

[0033] In this embodiment, the branch pipe 130 is welded to one side of the drain pipe 120, and the lengths of the hose 1 140 and the hose 2 150 can be selected according to the distance between the drain pump body 100 and the suction assembly 200. The connections between the above pipes are fixed by flanges and bolts.

[0034] like Figures 4 to 11 As shown, as a preferred embodiment of the present invention, the blocking assembly 330 includes a fixed seat 331, a sealing plate 332, a spring 333, a fixed shaft 334 and a blocking cylinder 335. The fixed seat 331 is vertically slidably installed in the mounting groove 322, the sealing plate 332 is locked on the surface of the mounting groove 322, a spring 333 is installed between the sealing plate 332 and the fixed seat 331, the blocking cylinder 335 and the fixed shaft 334 are evenly distributed in the square groove 321, the blocking cylinder 335 is rotatably installed on the outer wall of the fixed shaft 334, and filter holes 336 are distributed on the surface of the blocking cylinder 335, and both ends of the fixed shaft 334 extend into two symmetrical mounting grooves 322 and are fixedly connected to the two fixed seats 331 in the two mounting grooves 322 respectively.

[0035] like Figures 4 to 11 As shown, as a preferred embodiment of the present invention, fan-shaped scrapers 337 are evenly distributed in the square groove 321, and the two ends of the fan-shaped scraper 337 are fixed on the two ends of the fixed shaft 334. The fan-shaped scraper 337 is located on the outside of the barrier tube 335, and the inner wall of the fan-shaped scraper 337 is close to the outer wall of the barrier tube 335, and the inner diameter of the fan-shaped scraper 337 is slightly larger than the outer diameter of the barrier tube 335.

[0036] In this embodiment, when the drainage assembly 200 is pumping water in the tunnel, the water in the tunnel enters the drainage assembly 200 through the space between the two barrier cylinders 335 and the filter holes 336 on the barrier cylinder 335, so that the barrier cylinder 335 can block the fixed particles entering the drainage assembly 200, preventing them from entering the drainage assembly 200 and causing damage to the drainage pump body 100, thereby ensuring the drainage quality and efficiency of the drainage pump body 100 and extending the service life of the drainage pump body 100; When the circular block 320 rotates with the rotating cleaning mechanism 400, the circular block 320 drives the multiple barrier cylinders 335 to revolve synchronously. The barrier cylinder 335 in the revolving state will contact the solid particles distributed at its bottom, and the friction between the two will drive the barrier cylinder 335 to rotate freely on the fixed shaft 334, so that the fan-shaped scraper 337 can scrape the impurities retained on the surface of the barrier cylinder 335, ensuring the filtering efficiency and filtering quality of the barrier cylinder 335 itself. In addition, the barrier cylinder 335 can not only effectively intercept and separate the larger impurities in the accumulated water through the revolution and rotation, but also play a role in pretreatment and filtration, protect the pumps, pipes and other key equipment in the drainage system from wear and blockage, ensure the smooth operation of the drainage system, reduce the burden of the drainage device, and extend its service life, but also form a dynamic filtration effect, so that a layer of dynamic filter membrane is formed on its surface, so that the barrier component 330 is not easily blocked by impurities, further enhancing its interception ability for solid particles, protecting the internal structure of the drainage device, and at the same time improving the durability of the drainage device, ensuring the smooth progress of the drainage operation; At the same time, in order to prevent the fixed particles from damaging the barrier cylinder 335 in a rotating state, when the barrier cylinder 335 rotates and contacts the fixed particles, the fixed particles will drive the fixed shaft 334 to move upward through the barrier cylinder 335, and the fixed shaft 334 will squeeze the spring 1 333 through the fixed seat 331. At the same time, the spring 1 333 can also allow the barrier cylinder 335 to always contact with the solid particles during the rotation process through its own elastic force.

The exhaust and suction main pipe 210 is also connected to a control mechanism 500. Filter plates 240 are fixed on one end of the exhaust and suction main pipe 210 and the exhaust and suction auxiliary pipe 230 close to the exhaust and suction bucket 220. A rotating cleaning mechanism 400 is installed directly above the exhaust and suction bucket 220, and an annular sleeve 310 is installed directly below the exhaust and suction bucket 220.

[0039] In this embodiment, the drainage hopper 220 is located inside the water accumulation in the tunnel. The drainage pump body 100 can suck the accumulated water in the drainage hopper 220 into the drainage suction main pipe 210 and the drainage suction auxiliary pipe 230 by suction. The accumulated water then enters the hose 140 from the drainage suction main pipe 210 and the drainage suction auxiliary pipe 230. The accumulated water in the hose 140 enters the drainage pump body 100 through the water inlet pipe 110. The drainage pump body 100 quickly discharges the accumulated water inside it out of the tunnel through the drainage pipe 120, thereby realizing a rapid drainage operation of the tunnel. The position where the drainage and suction main pipe 210 is connected to the drainage and suction bucket 220 and the position where the drainage auxiliary pipe is connected to the drainage and suction pipe are both chamfered.

[0040] In a preferred embodiment, the diameter of the discharge suction main pipe 210 is larger than the diameter of the discharge suction sub-pipe 230.

One side of the mounting cylinder 410 is connected to the control mechanism 500, and the other side of the mounting cylinder 410 is connected to the discharge and suction hopper 220.

One end of the cleaning assembly 440 intermittently contacts the filter plate 240 and the inner wall of the discharge and suction hopper 220, and the other end of the cleaning assembly 440 is concentric with the circular block 320 and is fixedly connected.

[0042] In this embodiment, part of the accumulated water discharged from the drain pipe 120 will enter the branch pipe 130, and the branch pipe 130 will discharge the accumulated water into the control mechanism 500 through the hose 150. The control mechanism 500 will quickly discharge the accumulated water into the installation cylinder 410 and drive the rotating component 430 to rotate. The rotating component 430 drives the cleaning component 440 to rotate. The cleaning component 440 can not only intermittently scrape the silt on the inner wall of the filter plate 240 and the suction bucket 220 by rotating, so as to ensure the pumping quality and efficiency of the suction component 200 and improve the pumping efficiency and quality of the drainage device, but also drive the circular block 320 to rotate between the annular sleeve 310 and the suction bucket 220. The circular block 320 can drive multiple barrier cylinders 335 to revolve synchronously, so that the barrier cylinders 335 revolve and rotate at the same time, effectively intercepting and separating larger impurities in the accumulated water, playing a role of pretreatment and filtration, protecting the pumps, pipes and other key equipment in the drainage system from wear and blockage, and ensuring the smooth operation of the drainage system.

[0047] In this embodiment, the rotating shaft 432 drives the rotating frame 442 to rotate, and the rotating frame 442 drives the sliding column 444, the square scraper 445, the second spring 446 and the circular block 320 to rotate at the same time. The second spring 446 drives the square scraper 445 to always contact the inner wall of the suction bucket 220 or the filter plate 240 through its own elastic force. The square scraper 445 can intermittently scrape the sludge on the filter plate 240 and the inner wall of the suction bucket 220 by rotating, thereby ensuring the pumping quality and efficiency of the suction and discharge assembly 200, and improving the pumping efficiency and quality of the drainage device; When the square scraper 445 is scraping the sludge on the filter plate 240, the square scraper 445 first enters from the chamfered position on one side of the filter plate 240 and scrapes the sludge by rotating, and finally moves out from the chamfered position on the other side of the filter plate 240 and scrapes the sludge on the inner wall of the suction hopper 220.

[0048] In a preferred embodiment, the square scraper 445 can be replaced with other shapes that meet the usage requirements, such as a trapezoidal or conical shape.

[0049] like Figures 1 to 4As shown in FIG. 5 , as a preferred embodiment of the present invention, the control mechanism 500 includes a water inlet cylinder 510, a connecting pipe 1 520, a control frame 530, a delivery pipe 540, a connecting pipe 2 550 and an adjustment assembly 560. The water inlet cylinder 510 is fixed to the fixing frame 420 through the control frame 530, and the water inlet cylinder 510 is located on one side of the mounting cylinder 410. The connecting pipe 1 520 is fixed on the top of one side of the water inlet cylinder 510. The connecting pipe 1 520 is connected to the hose 2 150. 0 is connected, a connecting pipe 2 550 is fixed to the bottom of one side of the water inlet cylinder 510, one end of the connecting pipe 2 550 is connected to the discharge suction main pipe 210, a delivery pipe 540 is fixed to the other side of the water inlet cylinder 510, the delivery pipe 540 is connected to the installation cylinder 410, an adjustment component 560 is vertically slidably installed in the water inlet cylinder 510, the diameters of the connecting pipe 2 550 and the delivery pipe 540 are consistent, and the sum of their diameters is equal to the diameter of the connecting pipe 1 520.

[0050] like Figures 2 to 4 As shown, as a preferred embodiment of the present invention, the adjustment component 560 includes a fixed column 561, a sliding member 562 and a spring three 563. The fixed column 561 is vertically fixed in the water inlet cylinder 510 and parallel to the water inlet cylinder 510. A sliding member 562 in contact with the inner wall of the water inlet cylinder 510 is slidably installed on the fixed column 561. One end of the sliding member 562 is connected to the bottom of the inner wall of the water inlet cylinder 510 through the spring three 563. The sliding member 562 preferably adopts a rotating cylinder structure with a U-shaped cross-section.

[0051] In this embodiment, part of the accumulated water discharged from the drainage pipe 120 will enter the branch pipe 130, and the branch pipe 130 will discharge the accumulated water into the water inlet cylinder 510 through the hose 2 150 and the connecting pipe 1 520. In the initial state, the spring 3 563 drives the sliding member 562 to move upward through its own elastic force, so that the sliding member 562 can be located at the connecting pipe 2 550 at the bottom of the water inlet cylinder 510 for blocking, so that the water in the water inlet cylinder 510 can be prevented from entering the discharge suction main pipe 210, thereby ensuring that the water in the water inlet cylinder 510 can flow into the delivery pipe 540 normally, and ensuring that the rotating cleaning mechanism 400 can work stably; When the pumping efficiency of the drainage and suction assembly 200 is normal, since the diameter of the connecting pipe 1 520 is equal to the sum of the diameters of the connecting pipe 2 550 and the delivery pipe 540, the accumulated water in the water inlet cylinder 510 increases continuously, and the increasing accumulated water exerts pressure on the spring 3 563, so that the sliding member 562 can move downward in the water inlet cylinder 510, thereby releasing the blockage of the connecting pipe 2 550. Under the condition of ensuring the stable output flow of the delivery pipe 540, the excess accumulated water in the water inlet cylinder 510 can be discharged into the drainage and suction main pipe 210; When the pumping efficiency of the suction component 200 is poor, the accumulated water in the water inlet cylinder 510 continues to decrease, and the spring three 563 drives the sliding member 562 to move upward by releasing its own elastic force, so that the sliding member 562 can not only restore the blockage of the connecting pipe two 550, but also push the accumulated water on the upper part thereof, ensuring that the output flow of the delivery pipe 540 is always stable, and then ensuring that it can stably drive the impeller 431 to rotate. In this way, regardless of whether the suction component 200 is pumping water normally, the accumulated water in the water inlet cylinder 510 can always provide stable output power for the impeller 431, ensuring the stable rotation of the cleaning component 440 and the barrier component 330.

[0052] The working principle of the present invention is: Part of the accumulated water discharged from the drainage pipe 120 will enter the branch pipe 130, and the branch pipe 130 will discharge the accumulated water into the water inlet cylinder 510 through the hose 2 150 and the connecting pipe 1 520. In the initial state, the spring 3 563 drives the sliding member 562 to move upward through its own elastic force, so that the sliding member 562 can be located at the connecting pipe 2 550 at the bottom of the water inlet cylinder 510 for blocking, so that the water in the water inlet cylinder 510 can be prevented from entering the discharge suction main pipe 210, thereby ensuring that the water in the water inlet cylinder 510 can flow into the delivery pipe 540 normally; When the pumping efficiency of the drainage and suction assembly 200 is normal, since the diameter of the connecting pipe 1 520 is equal to the sum of the diameters of the connecting pipe 2 550 and the delivery pipe 540, the accumulated water in the water inlet cylinder 510 continues to increase, and the increasing accumulated water exerts pressure on the spring 3 563, so that the sliding member 562 can move downward in the water inlet cylinder 510, thereby releasing the blockage of the connecting pipe 2 550. Under the condition of ensuring the stable output flow of the delivery pipe 540, the excess accumulated water in the water inlet cylinder 510 can be discharged into the drainage and suction main pipe 210; when the drainage and suction assembly 200 is normal, the water in the water inlet cylinder 510 can be discharged into the drainage and suction main pipe 210. When the pumping efficiency is poor, the accumulated water in the water inlet cylinder 510 is continuously reduced, and the spring 3 563 drives the sliding member 562 to move upward by releasing its own elastic force, so that the sliding member 562 can not only restore the blockage of the connecting pipe 2 550, but also push the accumulated water on the upper part thereof, ensuring that the output flow of the delivery pipe 540 is always stable, thereby ensuring that it can stably drive the impeller 431 to rotate. In this way, regardless of whether the suction and discharge assembly 200 is pumping water normally, the accumulated water in the water inlet cylinder 510 can always provide stable output power for the impeller 431; The impeller 431 drives the rotating shaft 432 to rotate, and the rotating shaft 432 drives the rotating frame 442 to rotate. The rotating frame 442 drives the sliding column 444, the square scraper 445, the second spring 446 and the circular block 320 to rotate at the same time. The second spring 446 drives the square scraper 445 to always contact the inner wall of the suction bucket 220 or the filter plate 240 through its own elastic force. The square scraper 445 can intermittently scrape the sludge on the filter plate 240 and the inner wall of the suction bucket 220 by rotating, thereby ensuring the pumping quality and efficiency of the suction and discharge assembly 200, and improving the pumping efficiency and quality of the drainage device; The circular block 320 drives multiple barrier cylinders 335 to revolve synchronously. The barrier cylinder 335 in the revolving state will contact the solid particles distributed at its bottom, and the friction between the two will drive the barrier cylinder 335 to rotate freely on the fixed shaft 334, so that the fan-shaped scraper 337 can scrape the impurities retained on the surface of the barrier cylinder 335, ensuring the filtering efficiency and filtering quality of the barrier cylinder 335 itself. In addition, the barrier cylinder 335 can not only effectively intercept and separate the larger impurities in the accumulated water through the revolution and rotation, play a role in pretreatment and filtration, and protect the pumps, pipes and other key equipment in the drainage system from wear and blockage, but also form a dynamic filtration effect, forming a layer of dynamic filtration membrane on its surface, so that the barrier component 330 is not easily blocked by impurities, further enhancing its ability to intercept solid particles. At the same time, in order to prevent the fixed particles from damaging the barrier cylinder 335 in a rotating state, when the barrier cylinder 335 rotates and contacts the fixed particles, the fixed particles will drive the fixed shaft 334 to move upward through the barrier cylinder 335, and the fixed shaft 334 will squeeze the spring 1 333 through the fixed seat 331. At the same time, the spring 1 333 can also keep the barrier cylinder 335 in contact with the solid particles during the rotation process through its own elastic force; The above is the working principle of the tunnel drainage device used in the construction of the expressway.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
